Browser-local product-activity conversion
Convert EDI 852 to CSV, Excel, JSON, or XML
Export the canonical 112-field Smart Mapping or a separate source-ordered Raw representation.
Upload or paste an EDI 852, then choose Smart Mapping or Raw Mode. Automatic detection checks for exact ST01=852; you can also select Product Activity Data manually. Review the product-activity rows, generic validation findings, and source-grounded summary before downloading the format your analysis requires.
Smart Mapping and Raw Mode stay separate
Smart Mapping produces 112 ordered string fields for PRODUCT_ACTIVITY and SUMMARY rows. Raw Mode remains the independent physical-segment representation. There is no Key/All projection choice.
Canonical export formats
CSV preserves header order. XLSX keeps leading zeros, long numeric-looking IDs, 1.0, 1.00, 001.000, formula-shaped text beginning with =, +, -, or @, hostile text, and collection JSON as strings. JSON contains current canonical row objects. XML is canonical-row XML serialization—not native X12 XML, lossless X12 reconstruction, or implementation-guide XML.
Viewer and Data Editor preparation
Shared search, filter, string-aware sorting, editing, and edited export operate on distinct ProductQuantity, ActivityQuantity, ActivityDestination, and PerformanceCondition columns. Compact and nested collection JSON remains textual data.
Privacy and extreme XML
Mapping, validation, summary generation, and export semantics process payloads locally in the browser. Static assets and generic quota requests can use the network, so this is not an absolute security guarantee. Realistic XML is supported; characterized 50K monolithic XML can reach V8's maximum-string boundary and must fail boundedly rather than creating an arbitrary public transaction cap.
Convert an 852 for careful analysis
Open the EDI Converter, inspect rows in the Viewer, or consult the EDI 852 canonical data map before designing downstream calculations. The 852 reading guide explains product-versus-activity ownership, and the validation guide explains why structural validity is not proof of sales or inventory truth.
